INDICATOR-LOCK.

SPECIFICATION forming part of Letters Patent No. 499,501, dated J'une13, 1893.

Apnlication filed February 10, 1893. Serial No. 461,809. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM F. BEAsLEY, a citizen of the United States,residing at OX- ford, in the county of Granville and State of NorthCarolina, have invented certain new and useful Improvements inDoor-Locks; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My present invention relates to locks adapted to be used with doors,drawers, 85o., and it consists in a registering lock of the characterdescribed in Letters Patent of the United States, No. 220,124, grantedto H. Clarke, on the 30th day of September, 1879, the said lock having alocking plate secured to the barrel thereof, While the shell of the saidlock extends through the thickness of the door, &c., and projecting fromthe forward face thereof, serves as a handle therefor, and it furtheroonsists in the construction, arrangement and combination of the severalparts of which it is composed, as will be hereinafter more fullydescribed and claimed.

Referring to the accompanying drawings, in which corresponding parts aredesignated by similar marks of reference. Figure 1 is a perspective viewof a door having my invention applied thereto. Fig. 2 is a horizontalsection through the door and lock thereon, taken on a line -x of Fig. 3.Fig. 3 is a rear View of a door with my invention applied thereto withthe cover removed.

The door 1, is shown as contained in the suitable frame 2, the doorhaving a beading 3 thereon which covers the joint between the twoformer. A circular aperture 9 is cut in the door, through which projectsforwardly the shell 5, the forward end of the said shell being closed bya plate 6, formed by preference integral with the shell, while the rearend of the shell has the outwardly projecting annular flange 7 thereonwhich rests in a corresponding annular step 8 in the door andsurrounding the rear of the aperture 9. A block 10 iits within the rearof the shell 5, it having an annular iange 11 thereon, which rests overthe flange 7 on the shell, to which it is secured by rivets 12, althoughit is evident that the block may be secured within the shell by pinsprojecting through the walls of the shell and into the block (asindicated in dotted lines at 12, Fig. 2) in which case the flange 7 onthe shell may be dispensed with. The iiange 11 on the block 10 restswithin a step 13 in the thickness of the door, and surrounding theaperture 9, so that the rear face of the said block is iiush with therear face of the door, while the block itself, is by preference, of sucha thickness that the forward face thereof is either flush with theforward surface of the door, or a little in the rear thereof, so thatthe entire space in the said shell in front of the forward face of thedoor can be occupied by the indicating disks, to be hereinaftermentioned, which are visible through a glazed slot 14 in the shell. Abarrel 15 is mounted within the said shell, the forward end of the saidbarrel being journaled in an aperture 16a in the plate 6 of the cell,while a button 16 is rigidly secured on the said shaft near the rear endthereof, and is contained in a circular depression 17 in the forwardface of the block, the rear end of the barrel passing through anaperture 18 in the block to, the rear of the door, where it is squaredor reduced to other angular form. It will be seen that the button 16 bybearing on the block prevents the rearward movement of the barrel, andthat the shoulder 19 formed on the forward end of the barrel, by bearingon the rear face of the plate 6, prevents a forward movement of thebarrel, which is at the same time capable of rotating within the casing.Radial holes 20 are formed in the button 16 and in the rear portion ofthe barrel, in line therewith, the inner ends of the said holescommunicating with the longitudinal slot 21, which is formed within thebarrel and extends from the front thereof to near the rear, whilesimilar holes 22 are formed in the block 10 in alignment with the holes20. Springs 23, and pins 24, and 25 are contained, in the holes 2O and22 the springs 23 being adapted to be forced back, flush with thesurface of the bntton by means of a keyinserted in the said slot 21, asis described in the hereinbefore Inentioned patent to Clarke. A seriesof indicating wheels 27 are loosely journaled on the barrel, and have ontheirperipherya series of numbers O to 9 inclusive. The said wheels areadapted to be thrown on each revolution of the barrel,

IOO

by means of a series of disks 2S journaled on l a post 29 projectingforwardly from the forward surface of the block l0, as is also describedin the said Letters Patenti. The angular rear end of the barrel, whichas before stated projects to the rear of the door, has secured thereonthe locking plate 30, which is so mounted thereon, that when the barrelis in a position to be locked against rotation by the p1ns 24, thearc-shaped end of the plate proj ects beyond the edge of the door, andwhen the latter is closed, into a recess 30 in the door frame, thuspreventing the door from opening. It will be seen that by inserting thekey the barrel will be unlocked and capable of rotation, and that uponrotating it through a quarter of a complete revolution, the lockingplate will be so moved as to lie entirely loehind the door and clear thedoor frame, and I so adjust the registering mechanism that on thebeginning of this quarter revolution, the registering wheel will bethrown, thus rendering it impossible to open the door without throwingthe register, which will be detected by reading the state of theregister through the glazed aperture in the shell and comparing it withthe previous reading. It will be impossible to now withdraw the keyuntil the barrel is rotated through the remaining arc of two hundred andseventy degrees, again locking the door and bringing the holes 20 and 22again in line.

In order to prevent the removal of the screws 3l, which hold the shellin the door and which pass through the flange Il of the block lO, intothe thickness of the door, I by preference form the locking plate, asshown, that is to say in form of disk 32, of sufficient size to entirelycover the rear ot' the block l0 and iianges Il thereon in every positionof the barrel, the said disk having projecting therefrom the wing orlocking plate proper SO, while a single radial slot 33 is cut in thesaid disk, and is adapted to the rotation of the said barrel tosuccessively uncover the heads of the screws 3l. This permits theremoval and replacing of the shell on the door, but at the same timerenders it more difficult to remove the screws surreptitiously. It willbe seen that the projecting shell serves as a handle for the door.

In some eases where additional security from the unauthorized removal ofthe lock is required, I use the following construction, which is shownin Fig. 3. I cause the rear of the barrel to project a sufficientdistance to permit a second disk 34 of the same size as the disk 32, butwithout the wing 30, to be loosely mounted on the barrel between thedisk 32 and the rear face of the door, the said under disk being slottedas at 40, and having formed on its rear face an internal Jcrown gearing35, which is concentric to the barrel, and cutaway a portion of the rearface of the block, as at 3G to receive the pinion 37, keyed on thebarrel, and a driving pinion 3S,

loosely mounted on a post 39, projecting from the rear of the block, therelative size of the pinious 37, and 38 and internal gearing being suolithat it will requirea numberofrevolutions of the barrel to causeacomplcte revotion ol the under disk 3i, and thus, 4by continuedrotation of thebarrel,tl1eslot40inthe disk Se, and the slot 33 in thedisk 32, will be successively and simultaneously brought over theseveral screws, ttc., in the flange ll, which may be then unscrewed byinserting a screwdriver through the said slots, the great change in thestat-e of the register caused by the said rotation of the barrel,serving as a means of detection of the tampering with the fastening ofthe block. I may also cover the disks 32 and 3e in thc barrel by acasing Lil. secured in the rear face of the door, and provided withapertures 42, opposite to the screws in the flanges of the block, topermit their removal, the said casing being of a sul'licient size topermit the locking wing 30 to be. rotated under it, and in this case thedisk portion 32 of the locking plate 30 may be dispensed with, the saiddisk 32, serving when the casing Il is not used, as a cover for theunder disk 'When it is desired to use the double key system on a lockconstructed in this manner, I apply a second lock el to the door, thesaid lock having a spring pressed bolt 4t2, the projecting' end of whichis received in a recess t3 in the plate 32, it thus locking the plateagainst rotation, but it will be seen that by retracting the bolt 42 bya second key insorted in the lock il, and held in that position, theplate may be turned until the locking wing thereon has passed oppositethe bolt, when the bolt may be released by the second key, and will thenbear against the periphery ofthe wing, and will, upon the passage of thewing upon the continued rotation of the barrel, be pushed out and bearupon the periphery of the disk or plate 32, and will upon the completionof a locking rotation of the disk or plate, and when it has become fullylocked, slip into the recess 43, in the plate, thus again locking theplate against rotation.

IIavin g thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination in a door lock, and a shell adapted to projectforwardly through the door and serve as a handle, a rotating barrelprojecting through the said shell, a locking plate secured on the rearend of the said barrel, and a registering mechanism reccrding therotations of the said barrel and contained in the said shell,substantially as described.

2. The combination in a door lock, of a shell adapted to projectforwardly through the door and to serve as a handle, of a block securedin the rear end of the said shell and adapted tc be fastened to the rearof the door, a barrel passing through the front of the said shell, andthrough the block; a locking plate se- IOO cured on the rear end of thesaid barrel, and a registering mechanism contained in the said cell andadapted to register the rotations of the said barrel, substantially asdescribed.

3. The combination in a door lock, of a shell adapted'to project forwardfrom the face of the door, and to serve as a handle therefor of a blocksecured in the rear end of the said shell, and having an annular flangethereon adapted to be secured to the rear surface of the door; a barrelpassing through the front of the said shell and through the said block;a locking plate secured to the said barrel, and registering mechanismcontained in the said shell and adapted to register the rotations of thesaid barrel, substantially as described.

4. The combination in a door lock, of a shell adapted to projectforwardly from the face of the said door, and to serve as a handletherefor, of a block secured to the rear end of the said shell, andhaving an annular' flange thereon, adapted to be secured to the saiddoor; a

barrel journaled in the face plate of the shell and in the block, andprojecting to the rear thereof; registering and locking mechanism forthe said barrel, contained in the said shell, and a locking platesecured to the rear end of the said barrel, the said plate being of asufficient size to entirely cover the said blocks,
